Soil erosion and sediment export from agricultural lands has profound on and off-site consequences that threaten both the natural environment and effective sustainable resource management in Europe. Currently, modelled approaches using the Revised Universal Soil Loss Equation (RUSLE) to predict the spatial distribution of soil erosion produce annual average values of soil erosion with minor consideration of sub-annual variation in its ...

The effectiveness of soil-surface covers (e;g. geotextiles, rock fragments, mulches) in reducing runoff and soil erosion by water is often assessed only based on their cover percentage. However, some studies indicate that other characteristics, e;g. thickness, structure or vertical position of the surface covers in the soil toplayer, can also significantly influence their erosion-reducing effectiveness. Often rock fragments or mulches are partly ...

Soil erosion is a major problem leading to severe land degradation problems. To control these soil erosion processes, plant species can be used. Both above- and below-ground biomass can help to protect the soil. Plant roots can be very effective in stabilizing the soil against concentrated flow erosion and shallow mass movements. Most research on the erosion-reducing potential of plant roots was conducted on loamy soils and at present, ...

Description:The VPO uses the sediment model CN-WS for the modeling of soil erosion, sediment transport to the watercourses and the effect of erosion control measures. This CN-WS model is based, among other things, on the RUSLE equation. In this comparison, the crop and operations factor C is an important parameter that depends on cultivation choices and soil tillage. The C-factor is determined, among other things, by the soil cover by the ...

In many regions of the world, gully erosion is a process that is responsible for important soil losses and a majority of the sediments transported by river systems. Understanding and quantifying gully erosion (GE) rates and their contribution to catchment sediment yields (SY) is therefore of fundamental scientific importance, but also necessary for the development of suitable land use and catchment management strategies. Nonetheless, our ...

In the European framework directive Soil protection, wind erosion is considered as one of the main threats on soil quality in Europe. To delineate the areas susceptable to wind erosion in Flanders, Belgium, wind erosion is computed at the field level using a modeling approach. Erodibility measurements in the wind tunnel support the computer simulations.

The GOMEROS-project investigated how growing vegetables and maize can be successfully done under the new erosion regulations (Pillar I of the CAP), so that crop yield and quality are maintained while erosion is also effectively controlled. The mandatory anti-erosion measures have become stricter for plots with a very high (purple) and high (red) erosion risk since 2014. Farmers must choose measures from four ...

The aim of this project is the implementation of a TEAM project 2018 as part of the university cooperation for development of VLIR between the Universidad Mayor de San Adrés in Bolivia and the KU Leuven about the anthropogenic influence on erosion rates in a typical watershed for the development of strategies to reduce Land Degradation in the Bolivian Andes.

Sediment is the largest water “pollutant” by volume in the world, yet the limitations in current modelling processes still makes it impossible to quantity the amount of sediment eroded from land and transported in rivers. Sediment’s detachment, transport and deposition mostly take place within a thin near-bed layer. Therefore it is imperative for modelling processes to establish accurate representation of flow velocity and the rough bottom ...
